Window mastic for homes and businesses in Five Wents
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have cracked sealant at the sill ends and white mastic on grey or black frames, we can help.
Somewhere as small as Five Wents, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, you get the same 12-month guarantee in Five Wents and across Kent.

Do you need window mastic in Five Wents?
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Most people get in touch after spotting something like this:
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Whether you can choose the colour
- When the joint can take water or movement
- The length of the guarantee
- How the surfaces are prepared before sealing
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Five Wents, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Questions from Five Wents
Will you come out to Five Wents?
Yes. Five Wents is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Hollingbourne station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Rotten timber, which needs a joiner first
- Faulty window hardware
- Draughts through the window seals rather than the frame
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Patio & French doors
- Composite doors
- uPVC windows
- Aluminium frames

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy.

- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.

For landlords and businesses
Landlords and letting agents in Five Wents can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Aftercare tips
So the new joints stay in good condition:
- Do not paint over the silicone
- Make sure the drainage slots aren’t blocked
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames do not stay wet inside
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Window mastic in Five Wents: local notes
Historic houses like Stoneacre (about 1.7 miles north) are a reminder that the area around Five Wents has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Sutton Valence Primary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Hollingbourne station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
